Life-changing High Protein Banana Bread

Do you ever crave banana bread? The almost intoxicating smell that fills the house while it’s baking, the deliciously dense texture, and perfectly sweet flavour? I do. Yes, I sure do. 

Banana bread is definitely one of my favourites and I’m revamping this recipe yet again for the blog today… I honestly feel it’s a recipe that can be changed so many ways and today I’ve seriously taken it up a notch. Did someone say cashew cream cheese frosting?! 

fresh baked protein banana bread loafThis bread is delicious, super moist, dense, hearty, and full of protein, complex carbohydrates, and a nice amount of healthy fats. 

Years ago I would always order the “reduced-fat, healthy”  banana chocolate chip coffee cake at Starbucks (before I knew any better!) but now I almost always make my own at home. That banana bread was delicious, but one day my curiosity got the best of me and I looked up the nutritional details on the Starbucks website and let’s just say, like usual, “reduced fat” = “a crap-load of sugar” and seriously, there’s absolutely nothing wrong with dietary fat anyways, so the whole “reduced fat” label (especially when one piece is still 400 calories) is just plain silly. A perfect example of deceptive food-industry marketing.

I decided shortly after my Starbucks awakening that I’d have to find or create a better, more balanced and healthy banana bread. To my delight I stumbled across a recipe from Brittany at Little B’s Healthy Habits that seemed like a good starting point (she has since made her blog private and it can’t be accessed anymore!).

Brittany’s recipe for high protein banana bread was packed with protein from the addition of whey protein powder and Greek yogurt. Unfortunately, due to my dairy allergy I can’t do either so instead I’ve created a couple adaptations based off of Brittany’s banana bread recipe that are dairy free and contain plant-based protein powder and egg whites to bring in a great amount of protein.

What Makes This Banana Bread High Protein?

  • Protein powder – Vanilla plant-based protein powder isn’t all created equal though so my suggestion is to stick with a powder that is either brown rice based, (organic) soy based, or pea based for this recipe. You can also use vanilla whey protein powder if dairy is not an issue.
  • Egg whites – Egg whites are a great, affordable source of protein that really add to this recipe. 
  • Yogurt – If you are A-ok with dairy, you can opt for fat-free (0%) plain Greek yogurt, which also adds an additional boost of protein. If not, no problem – you can simply substitute it with coconut yogurt, though you will lose a few grams of protein and the bread will turn out a bit more dense and fudge-y with this option.
  • Protein icing – Feeling a little extra? While the cashew cream cheese icing is optional, it brings up the protein a bit more as it contains both vanilla protein powder and cashew nuts.

The wonderful thing about protein packed banana bread is that it helps keep blood sugar levels stable which can in turn prevent sugar cravings. When I used to work with nutrition clients I would always assess their daily protein intake (especially if sugar cravings were an issue) and it was amazing how often cravings and mindless snacking would disappear when protein intake wasn’t lacking. 

Healthy dietary fats can also help with cravings as they make you feel more satisfied, full, and slow the release of sugars into the blood stream. The cashews in the delicious dairy free cream cheese frosting for this banana bread bring in healthy fats (and some more protein!), and blend perfectly with vanilla protein powder, a touch of vanilla extract, maple syrup, and almond milk.

The frosting is totally optional for this recipe as it makes the loaf more indulgent and a touch messy (but really, does that even matter when it tastes so darn good?!).

Tips for this Banana Bread

  • Yogurt type –  You have the option to use either plain 0% Greek yogurt or coconut yogurt, which is higher in fat. The Greek yogurt will give the bread a lighter, airier consistency whereas the coconut yogurt is going to make the bread more dense and fudge-y. You will also probably need to increase cooking time with the coconut yogurt again because the fat content is higher.
  • Protein powder – The type and brand of protein powder you use in this recipe won’t really change the texture but it will affect the flavour as different brands taste differently. Just choose your favourite. (One exception: I don’t recommend using coconut-based protein powders as they’re too absorbent in this application.)
  • Cooking time – My suggestion is to not stray from the recipe too much with substitutions and cook the bread for as long as you need until a toothpick pulls clean from the centre of the loaf, checking it often.

If you love banana bread as much as I do and want to increase your protein intake to ward off sugar cravings, this protein packed banana bread is a perfect way to do just that! Be sure to pin the photo below the recipe to save this post for later and of course, share the love!

Banana Bread

  • 2 ripe bananas
  • 3/4 cup of oat flour
  • 6 grams granulated stevia OR 1/2 cup coconut palm sugar (using coconut palm sugar will make the loaf a darker color)
  • 1 teaspoon of baking soda
  • 1/4 teaspoon salt
  • 3/4 cup vanilla protein powder (whey or plant-based - avoid coconut based protein powders)
  • 1 cup of 0% fat Plain Greek yogurt OR 3/4 cup plain coconut yogurt
  • 1/3 cup egg whites
  • 1/4 cup of unsweetened applesauce
  • 2 teaspoons of pure vanilla extract

Cashew Cream Cheese Frosting (Optional)

  • 1 tablespoon pure maple syrup

Optional Garnishes:

  • Sliced banana
  • crushed walnuts

  1. Preheat oven to 375 degrees.
  2. Pace bananas in a mixing bowl and mash until you have a thick pudding-like consistency.
  3. Add all remaining banana bread ingredients to bowl and mix until well combined.
  4. Grease two small loaf pans (8" x 2 1/2") with coconut oil or line with parchment paper (alternatively you can use one larger loaf pan but this will increase cooking time)
  5. Divide batter between both pans and bake for 25 minutes (if using 0% Greek yogurt) or 40 minutes (if using coconut yogurt) or until a toothpick pulls clean when tested.
  6. While the banana bread is baking prepare the cashew cream cheese by soaking the cashews then draining and adding to a high speed blender with the remaining ingredients.
  7. Blend until completely smooth, transfer to a bowl then set in the fridge to chill.
  8. When bread is done baking, remove from oven and cool completely before frosting with the cream cheese and garnishing.

  • You weren’t lying when you said ‘best ever’ – this is the best banana bread I have ever made. Subbed the applesauce for another banana, added a shot of espresso and a cinnamon swirl, and a teaspoon of baking powder. It came out like a dream. Sending this recipe to everyone!

    • Hi Jessica, I’m not sure about swapping almond butter for Greek yogurt. They are very different in texture and consistency so I don’t think it would work. Let me know if you try!

  • Hi! I made this banana protein bread with some alternative ingredients that I had in the fridge. Instead of Greek yogurt, I used 1c of skyr 4%. Thicker consistency so it seemed to make the bread super moist and it was excellent! I didn’t have whole wheat flour so I used almond flour which gave the bread a nice texture. I had bobs red mill protein pancake mix LOL so I used about 2tbs of that. Instead of puréed apple sauce, I used two small peeled apples and throw into the blender with all the wet ingredients. I used honey instead of sugar & added cinnamon, nutmeg and chocolate chips, topped some sliced almonds and cashews. No frosting. This is by far the best protein banana bread I have ever made. THANK YOU!

    • Hi Lisa, the nutrition will depend on how you make the recipe as there are a lot of variations within the recipe. You can add the ingredients you use into an online fitness calculator like My Fitness Pal to figure out the accurate nutrition based on which ingredients you end up using!

  • I made it today and must say it was very good indeed, far exceeding my expectations. Why should we avoid coconut protein powders,? I am new to all this. keep up the excellent work , well done!!

    • Hi Paul! Glad you enjoyed it. I recommend avoiding the coconut powder for this recipe because it’s much more absorbent and can make the bread dry!

  • Christal,

    This recipe is fantastic! It’s so delicious, moist, and guilt free. Everything I could ask for in a dessert recipe.

    I’ve made it three times now. I omitted the applesauce, used MusclePharm Combat protein powder (cookies and cream flavor, and added cacao nibs on top of the batter before baking and over the frosting.

    Thanks for sharing!
